Benefits of technology

This configuration simplifies manufacturing, reduces alignment points, and prevents color shifts and vibrations, enhancing maintainability and image stability.

Problems solved by technology

In such image forming apparatuses, depending on a layout of the apparatus, maintainability of the latent image carrier and various types of peripheral devices such as a developing device disposed at the periphery of the latent image carrier may degrade because the optical writing unit comes in the way as an obstacle.
This may result in an increase in manufacturing cost and the like.
As a result, problems such as color shifts occur.

Embodiment Construction

[0031]Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0032]FIG. 1 is a schematic of a printer 100 according to an embodiment of the present invention. The printer 100 includes four process units 1Y, 1M, 1C, and 1K that form toner images of yellow, magenta, cyan, and black (hereinafter, “Y, M, C, and K”). The four process units mutually use toners of different colors of Y, M, C, and K, otherwise they have the same or substantially similar configurations. The process units are replaced when the toner runs out. For example, as shown in FIG. 2, the process unit 1K that forms a K toner image includes a photosensitive body 2K that is a latent image carrier in a drum shape, a drum cleaning device 3K, a neutralizing device (not shown), a charger 4K, and a developing device 5K. The process unit 1K that is an image forming unit, is attachable and detachable to and from the printer main body, and consumables can be replaced at one...

Abstract

An image forming apparatus includes a holding mechanism that holds an optical writing unit such that, at an operating position, the latent image writing unit is supported at three points with respect to the apparatus main body, and the latent image writing unit and the rotation axis are not in contact with each other.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to and incorporates by reference the entire contents of Japanese priority document 2007-246938 filed in Japan on Sep. 25, 2007.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an image forming apparatus such as a copier, a facsimile apparatus, a printer that can retract a latent image writing unit to a retracted position from an operating position.[0004]2. Description of the Related Art[0005]In typical electrophotographic image forming apparatuses, a configuration in which a latent image is written on a uniformly charged latent image carrier with a latent image writing unit has been widely adopted. The latent image carrier is generally a photosensitive body and the latent image writing unit is generally a laser writing device. In such image forming apparatuses, depending on a layout of the apparatus, maintainability of the latent image carrier and vari...
